About Arbitrum

Arbitrum is a Layer 2 (L2) blockchain protocol built on top of the Ethereum blockchain that allows Ethereum transactions to be processed more efficiently. 

By increasing the amount of transactions Ethereum can process, as well as the speed with which it can process them, Arbitrum has the additional benefit of reducing transaction costs, known as gas fees, associated with using Ethereum and its various decentralized applications.

Arbitrum also allows developers to create and execute their own Ethereum-compatible smart contracts. These can be programmed to run decentralized applications that can interact with the broader Ethereum ecosystem without bogging down the main blockchain’s performance.

Swap Arbitrum for other assets

After you buy Arbitrum, you can trade it for fiat currencies and other cryptocurrencies. Kraken offers over 200 Arbitrum trading pairs so you can move in and out of the market with ease.

Crypto Asset General Risks

  • Investing in crypto assets is risky and each token can have its own set of risks. Below is a list of risks that generally apply to all crypto assets:
  • Volatility: The performance of crypto assets can be highly volatile, with their value dropping as quickly as it can rise. You should be prepared to lose all the money you invest in crypto assets.
  • Lack of protections: Crypto asset investments are unregulated and neither the Financial Services Compensation Scheme (FSCS) nor the Financial Ombudsman Service (FOS) will assist or protect you in the event something goes wrong with your crypto asset investments.
  • Liquidity: Some crypto asset markets may suffer for low liquidity which could prevent you buying or selling your crypto assets at the price you want or expect.
  • Complexity: Specific crypto assets may carry with them specific complex risks that are hard to understand. Do your own research and if something sounds too good to be true, it probably is.

Don’t put all your eggs in one basket: Putting all your money into a single type of investment is risky. Spreading your money across different investments makes you less dependent on any one to do well.
